如何在Kotlin中使用Retrofit获取响应头？

dependencies {
    implementation 'com.squareup.retrofit2:retrofit:2.9.0'
    implementation 'com.squareup.okhttp3:okhttp:4.9.0'
    implementation 'com.squareup.okhttp3:logging-interceptor:4.9.0'
}

val retrofit = Retrofit.Builder()
    .baseUrl("https://api.example.com/") // 设置API的基本URL
    .client(OkHttpClient()) // 使用OkHttp作为HTTP客户端
    .build()

interface ApiService {
    @GET("endpoint")
    fun getResponse(): Call<ResponseBody>
}

val apiService = retrofit.create(ApiService::class.java)
val call = apiService.getResponse()

call.enqueue(object : Callback<ResponseBody> {
    override fun onResponse(call: Call<ResponseBody>, response: Response<ResponseBody>) {
        val headers = response.headers() // 获取响应头
        // 处理响应头的逻辑
    }

    override fun onFailure(call: Call<ResponseBody>, t: Throwable) {
        // 处理请求失败的逻辑
    }
})
